.To all whom it may concern.-

Be it known that I, JACOB MERSEREAU, a citizen of 'the United States, and a resident of Orange, Essex county, and State of New J ersey, have invented anew and useful Improvement in Siphon-Bottles, of which the following is a specification.

The invention relates to the valve mechanism of siphon-bottles, being an improvement upon Letters Patent No. 361,400, granted to C. De Quillfeldt, dated April 19,1887, and consists more particularly in the construction of the valve proper in reference to its adj ustment in relation to its carrying spindle and to the discharge passage, and also to render 'the same more durable and practical for the 'tube which connects with said top-piece h to communicate with the discharge spout, and through which the liquid is passed from ,the bottle to be discharged. The above parts are of usual construction and not of my present invention.

d is the valve which isadapted for shutting off or admitting of, discharge of the liquid through the discharge spout, andis carried by a vertically moving spindle d located in the neck of the top-piece b, which is adaptedto be moved in one direction to open the valve, by means of a lever cl2 having suitable connection therewith at one end as shown, and at its opposite or free end projecting from the top-piece h through an opening therein,

l in a convenient position to be operated. This spindle d is yieldingly held. in a normal raised position to hold the valve in a closed positionby means of a coiled spring cl3 which engages at one end with a collar or raised Serial No. 478,375. (No model.)

projection onthe latter to hold the same in such described position. A

The valve d consists of a flexible or elastic spherical shaped body, preferably formed of rubber, which is located on a spindle e having a screw-threaded end as a means for adj ustable and detachable connection with the spindle d. This adjustment of the valve in its relation to the spindle d is essential for the purpose of allowing the valve to be properly adj usted to its seat when the parts are assembled, and .also to allow for wear and other changes caused to the rubber by continued use as will be readily understood. p

It has been found in practice that When the valve is loose upon its stem as shown and described in said Letters Patent No'. 361,400, it is liable to be blown orforced'from its positionon the stem by the force or action of the liquid thereon when lling the bottle, which is accomplished by depressing the valve and forcing the liquid through the spout; and is also liable to. be disconnected from the stem by reason of the latter being drawn therefrom by the upward action of the spring d3. It is also' necessary to remove the valve from its stem in order to reach the latter for the purpose of adjustment, thus making it difficult to properly and accurately adjust the same, as it is obvious that .it is difficult to accurately adjust the position of the valve in relation to its seat whenthe latter is removed from its stem, the operation often requiring the removal of the valve from its stem lseveral times before it is properlyadjusted. In order to obviate such objectionable features, I have formed the stem with one or more ribs or collars e?, and form or cure the rubber valve perman-ently thereon, such ribs or projections serving to hold the valve firmly and prevent its slipping or otherwise moving on the stem. I also provide the stem with a slotted head e', which is not covered by the valve: By this construction the valve may be readily and accirately adjusted by means of a screwdriver or similar suitable tool, and is firmly held in position.

Another feature of my invention also con sists in the construction or formation of the lever d. Heretofore, the upper surface or y edge of such lever has been formed as shown by the dotted line in Fig. l, in such manner thatthat portion ot' the hand between thethumb and forenger has been liable to be caught and pinched between the upper end of the slot in which the lever moves and the lever, when operating` the latter, as will be readily understood. In order to prevent liability of such accident, I have provided the lever witha gnardf thereon, consisting' of a raised tapering projection which extends above the end Wall of the slot against which the lever strikes as clearly shown, and forms a guard to prevent the hand from getting caught between said engaging surfaces asV Will be readily understood.

Having thus set forth my invention,whatl claimas new, and desi/re to secure by Letters Patent of the United States, is Y l. In a Siphon-bottle, the combination of the top-piece b having a discharge passage, a

vertically moving spindle, an operating lever having connection with the latter, "and a valve,

vconsisting of a screw-threaded stem adapted JACOB MERSEREAU.
